e CANE MILL.

Application led July 21,

To all whom t may concern."

`Be it knownthat I, LUIs DIAZ HIDALGO, a citizen of Cuba, residing atHabana, in the Republic of Cuba, have invented a new and useful CaneMill, of which the following is a specification.v

The device :formingv the. subject matter of this application is a caneAmill andthe object 0f the invention is to improvethe mechanism wherebythe upper roller is heldfunder hydraulic pressure. In the drawings:.-Figurel isa vtop plan; Figure 2 is a vertical"longitudinal sectionwherein parts are shownfin elevation vliligure,

3 isa fragmental transverse section depicting the meanswhereby themovement 'be- Y* tween parts of the hydraulic pressure member isprevented. Y

As usual, the mill comprises a frame. including afbase 1` and standards2 secured to the-base, the standards being surmountednby caps 3 held inplace by b o lts,4'.j-I :Vertical guideways 5 are fashionedjin-thestandards 2.

The numeral 12 marks a lower shaft supported at 11 for rotationwithinthe guideways 5. A bottom roller 19 is mounted on the shaft 12 torotate with the shaft.

Upper bearings 21 aremounted to move in the guideways 5 of the standards2. The numeral 24 designates a power-driven upper shaft journaled in thebearings 21. A roller 34 is carried by the shaft 24 and rotates'therewith, the roller 34 being of considerably less diameter than thebottom roller 19.

The caps 3 are provided with vertical passages 37 enlarged at theirupper ends to form chambers 38. The caps 3 are provided withcircumferentially spaced lugs 39 projecting into the chambers 38. Ineach chamber 38 is located a head 40 having eyes 41 whereby it may bemanipulated, the head having lugs 42 engaged beneath the lugs 39 and ofsuch Size as to move vertically between the lugs 39 when the head 40 isrotated so that the lugs 42 are no longer beneath the lugs 39. The head40 is supplied with a reduced piston 43. A cylinder 44 is seated in thechamber 38 and includes a reduced neck 45 extended into the passage 37.The cylinder 44 is adapted to slide vertically on the piston 43. Apacking 55 is held by a plate 56 and a securing member 57 to the lowerend of the piston 43 and has a depending flange bearing against the sidewall of the cylinder 44 to aiord a fluid-tight joint. The cylinder 44includes 1920. A`sefia1z-1w 397,889.

ALootl48-1isz.thrieaded for adjustment yinto the member 47, as indicated' at49 andhas in italowenend; a'cnncaved seat 50 adapted t0coloperate-withafv convened blockk 51' mounted on the` .bearing-L21f.AY.

When it is desired t0` adjustthe: eliective Rotationy isimparted to gtheshaftv 24 and length' -of themovablemember of the hy- .f

drulie .presatthenpartp `.48 maytbe threaded upwardly,fv .Qligdownmldly,inf .the g part 47. .When theaforsaidf.adjustment has been made, thelocking strip 53 may be seatedI in one of the notches 52 of the member48, the strip being attached to the element 47 by means of the securingelement 54.

Should it be desired to remove the cylinder 44, the head 40 may berotated until its lugs 42 no longer are beneath the lugs 39 whichproject into the chamber 38. Then, the head 40 may be removed, the lugs42 on the head passing upwardly between the lugs 39 on the cap 3.

When the mill is in operation, the foot 48, the member 47 and thecylinder 44 are in almost continuous vertical movement. In order topermit the aforesaid movement, the caps 3 are provided at their innersides with vertically elongated slots 58 receiving nipples 59 whichcommunicate with the cylinders 44, the nipples being carried by thecylinders. The main pressure pipe is denoted by the numeral 60 and isconnected with the nipples 59 by flexible tubes 61, to the end that thecylinders 44 may move vertically with respect to the pipe 60, the latterelement being fixed, ordinarily.

Having thus described the invention, what is claimed is:-

1. A hydraulicpress comprising a movable member made up of two partsthreaded together to adjust lone of said parts with respect to eachother, and a locking device connecting said parts, releasably, toprevent threaded movement vtherebetween.

2. A hydraulic press comprising a `frame having a cavity, there being plugs on the frame, the lugs projecting linto the cavity, a head in thecavity and piston, the head having lugs engaged with the lugs on theframe, the yhead being rotatable, whereby the lugs on` the head may passupwardly between the lugs on thetrame when the head is raised, acylinder slidable in the cavity kand slidable onpthe piston, and meansfor supplying y pressure" to the cylinder. V v k:

3. A hydraulic press comprising a frame having a cavity, therebeingvlugs on the frame, the lugs projecting into the cavity, a head inthe cavity and having lugs engaged beneath the lugs on the frame, thehead being rotatable to dispose the lugs thereof out of alinement withthe lugs on' the frame and to permit a removal of the head, a memberslidable in the cavity, and means or supplying pressure to the spacebetween the said member and the head, said, member comprising upper andlower parts threaded together for adjustment, and means on said partsfor holding them releasably against relative threaded movement. j I A 4.In a device of the class described, a main member having a passageenlarged at one end to form a chamber, said member ben ing provided withcircumferentially spaced provided with a fixedl lugs projecting into thechamber, a head having lugs engaged beneath the lugs of said member, thehead having a reduced piston, a` cylinder seated in the chamber andmovable therein, the cylinder receiving the piston, the cylinder havinga reduced neck extended into the passage, a hollow member slidable inthe passage, means for securing the hollow member to the reduced neck ofthe cylinder, a Jr'oot threaded into the hollow member and provided witha concaved seat, the ootbeing provided in its end with a notch, alocking means secured to the hollow member and engaged with the notch tohold the foot against rotation, a convexed pressure member cooperatingwith the seatoi the foot, and means for supplying pressure to themovable cylinder.

. 5.1A hydraulic press comprising a fixed piston, a cylinder slidable onthe piston and including parts threaded together for adjustment, meansfor holding said parts against relative threaded movement, and meansvfor supplying pressure to the cylinder to cause it to move with respectto the fixed piston.

In testimony that I claim the foregoing as my own, I have hereto axed mysignature in the presence of two witnesses.
